After buying two servings of the finished forging fluid as a reference, Aaron walked to the place in the current area that specializes in selling materials for concoction of forging fluids.

The finished product of forging body fluid, compared to the materials for preparation, is much more expensive, just the two copies that Aaron bought just now, if he bought the materials himself to make the preparation, it only needs about one-third of the price of the finished product.

It's not particularly difficult to say that it is difficult to concoct forging body fluids, but it is impossible to say that it is easy, but compared to some complex potions made by Aaron before, it is much simpler, and with the auxiliary function of the chip, it is not difficult to achieve a 100% success rate.

For the vast majority of ordinary people, buying finished products is definitely the first choice, but for Aaron, it is definitely more cost-effective to make it himself, and he also needs to improve and optimize it himself, so it is not what he wants to buy finished products directly for use.

A short time later, Aaron came to a shop that sold materials, and saw him come in, and he came out to meet a young man, tall and thin.

The tall and thin man immediately greeted him and said politely, "This gentleman, what do you need?"

"You have those materials here to prepare high-grade forging body fluids, give me a list, and I'll choose for myself. Aaron glanced at the tall and thin man and replied.

"Okay, no problem, you wait a minute. The tall and thin man nodded when he heard this.

After a while, the tall and thin man took a large list, which listed the names of dense materials, there were a lot of high-grade brute essence blood, and even more those auxiliary materials used for concoction, there were more than two hundred types.

"These, these, and these, all of them are twenty copies for me, as for the blood of these ten essences. Prepare me a ten-portion ...... too" After reading the list of materials for a while, Aaron pointed to some of the materials on it and instructed the tall and thin man.

All of Aaron's words were the highest among them, and there were quite a few of them, after the tall and thin man listened. I couldn't help but be a little dumbfounded: "You really want so much?"

"Do you think I'm joking?" Aaron looked at him with a serious expression.

When the tall and thin man heard this, he was slightly embarrassed, and said, "The number of materials you want is relatively large, I have to confirm whether the quantity is enough, please wait a while, I will be back soon after confirming......"

The list of materials is now available, and it is a question of whether there is enough or not enough, so the tall and thin man needs to go and make sure.

"Okay, there you go. If the quantity is not enough, you can get me as much as you have now, and you can calculate the price first. Hearing this, Aaron nodded and said.

"Okay, no problem!" the tall and thin man nodded in response.

The tall and thin man had been gone for a while, and it was about four or five minutes before he returned, followed by two more people. Carrying a large box containing exactly the materials Aaron had asked for.

"Sir. The things you want are all in this box, the amount is just enough, the price is a total of three million gold coins, since you spend more than one million gold coins here at one time, we will give you a discount, only two million gold coins...... "After the two of them put the box on the ground. The tall and thin man then stepped forward and said to Aaron.

Aaron didn't want to confirm whether the contents of the box were enough, in the Dilong Firm, there was no need to worry about being cheated, and it was such a large amount of materials. There is no way to cheat.

"Take this card......" The thing was delivered, and Aaron took out the silver asset card and handed it to the tall and thin man.

The tall and thin man carefully took the asset card handed by Aaron, took it to deduct the amount of consumption this time, and then returned it to him, and also took out a small purple metal card: "Sir, this is our VIP card here, if you come here in the future, with this card, no matter how much money you buy, you can get a discount on the price......"

Aaron nodded, took the VIP card casually, put it away without looking at it, and then turned to leave with the large box of materials.

Looking at Aaron's distant figure, the tall and thin man smiled and said to himself: "I'm really lucky today, I met someone with a generous shot, and my commission this time must be the highest!"

Aaron left the Dilong Firm and rushed to his lodgings, eager to begin his research.

This time he came to the Dilong Trading Bank, and Aaron directly spent more than half of the gold coins deposited yesterday, and there were only nearly two million left in the trading bank.

However, there are a lot of things he bought this time, enough for him to study for a while, and he doesn't have to come over again in a short time.

"Let's start with the auxiliary materials......" After returning to his residence, Aaron took out the large box and placed it on a large table, then opened it, and took out the blood of the essence of the brute beasts first, and put it aside for the time being.

Among these materials, the most valuable ones are the essence blood of those high-level brute beasts, and all the others add up, at most, it is one-tenth of the total price, or even less.

In his previous research halfway, Aaron had been focusing on those auxiliary materials, and now it is the same, these auxiliary materials are not very valuable and can be squandered safely.

As for the essence of blood, Aaron plans to wait for future research and breakthroughs before starting, not using these high-level ones for the time being, and starting with the remaining middle and low-level ones.

Half a month ago, Aaron was stuck in one place during the experiment of essence blood, and he couldn't break through, and now he has almost a little eyebrows.

He found that the key problem should be in those auxiliary materials, so Aaron bought a large number of high-level auxiliary materials this time, hoping to find a breakthrough from these materials.

After removing some of the ancillary materials from the crate, Aaron began to do some basic processing for further refinement.

According to Aaron's current understanding, the auxiliary materials rely on some effective extracts contained in them, and the most critical part of the preparation of forging body fluids is these extracted ingredients.

What he has to do now is to extract these extracted ingredients from which auxiliary materials, and to make them as pure as possible, without other impurities.

It is not a simple matter to completely remove other impurities, at least Aaron has not succeeded once so far, and those extracted before have more or less impurities, and there is no way to eliminate all impurities...... (To be continued......)
